Caladenia attingens, commonly known as mantis orchid, is a species of flowering plants in the orchid family Orchidaceae and are endemic to the south-west of Western Australia. There are three subspecies, each of which has a single hairy leaf and one or two brightly coloured flowers with upswept sepals and a labellum with long, comb-like fringes. The subspecies differ in size, distribution and habitat.

Description

Caladenia attingens is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf Шаблон:Convert long and Шаблон:Convert wide. The lower part of the leaf often has reddish blotches.[1][2][3][4]

There are one or two flowers on a hairy spike Шаблон:Convert high, each flower Шаблон:Convert long and Шаблон:Convert wide. The flowers are green, white and yellow with reddish-purple areas. The dorsal sepal is erect, sometimes curves forward, Шаблон:Convert long, Шаблон:Convert wide with a swollen glandular tip Шаблон:Convert. The lateral sepals are Шаблон:Convert long, Шаблон:Convert wide and upswept with a glandular tip similar to the one on the dorsal sepal. The petals are Шаблон:Convert long, Шаблон:Convert long, spread widely and usually lack a glandular tip. The labellum is greenish-yellow with a red tip and four or more rows of dark red calli along its centre. The sides of the labellum bear long, green, comb-like teeth. Flowering occurs between August and November.[1][2][3]

Taxonomy and naming

Caladenia attingens was first formally described by Stephen Hopper and Andrew Brown in 2001 and the description was published in Nuytsia.[5] The specific epithet (attingens) is a Latin word meaning "reaching to" or "attaining", referring to the calli which extend as far as the tip of the labellum.[2]

When Hooper and Brown described the species, they also described two subspecies, C. attingens subsp. attingens[6] and C. attingens subsp. gracillima.[7] Since then, a third subspecies has been described by Andrew Brown and Garry Brockman and given the name C. attingens subsp. effusa.[8]

Distribution and habitat

Mantis orchids occur between Perth and Israelite Bay, growing in a range of habitats, depending on subspecies.[1]

Conservation

All three subspecies of Caladenia attingens are classified as "Not Threatened" by the Western Australian Government Department of Parks and Wildlife.[9]
